Trenz Electronic USB drivers for Windows 7 are installed as certified drivers on Windows 8 too; the installation of Windows 7 drivers on Windows 8 follow the same procedure. For the other two operating systems (XP and Vista), there are some differences, but the skeleton of the procedures is the same as Windows 7/8. The further possibility that exists in Windows 7 and Windows 8 is the automatic update from Internet (Windows repository of certified drivers, Windows Update). 2 Device Drivers To provide a convenient interface between host computer and Trenz Electronic USB modules, suitable drivers shall be installed on the operating system. There are two drivers that work with Trenz Electronic USB modules: 1. a generic Cypress USB driver, which works with default USB controller configuration; 2. a dedicated Trenz Electronic USB driver, which works with custom USB controller firmware. The generic Cypress USB driver is used only for initial USB microcontroller programming and it is not needed for a normal work flow. Most users need to install only the dedicated Trenz Electronic

2 USB driver. 2.1 Dedicated Trenz Electronic USB Driver Installation Hardware and Firmware Setting Previously, Trenz Electronic USB modules shipped with a DEWESoft USB firmware and a DEWESoft USB Vendor ID / Device ID pair programmed. Now, all Trenz Electronic USB modules ship with a Trenz Electronic USB firmware and Trenz Electronic USB Vendor ID / Device ID (VID = 0x0bd0, PID = 0x0300) pair programmed. Before connecting the USB cable, check that EEPROM switch is "ON" (USB controller connected to EEPROM). Refer to your module manual for switch location Windows 7/ Initial Part, Windows 7/8 Connect the USB cable and wait until the operating system detects new hardware. At this point, two outcomes are possible. 1. If there is an Internet connection and Windows parameters are correctly set, the driver is automatically downloaded from Microsoft Update and installed. Even if correct parameters are set, it may happen that the operating system informs you that is unable to install the device. In this case, you can force this search (see Force the online search) 2. The operating system informs you that is unable to install the device. For the first outcome, see Windows 7/8 Installation online, automatic. Hereunder it is explained what to do for the second outcome. Open Device Manager using this procedure: Start\Control Panel\System and Security\System\Device Manger (or write devmgmt.msc in the line Search programs and files to go directly to the Device Manager). The device is registered under Other Devices in Device Manager with a yellow triangle with! symbol. If you right click it and then select Properties, you can read as Device Status: The drivers for this device are not installed. (Code 28) There is no driver selected for the device information set or element. To find a driver for this device, click Update Driver At this point you shall click Update Driver. When the hardware assistant starts, answer its questions as shown in the following example.

32 Advanced Operations If the user wishes to go back to a former device driver, it is recommended to uninstall the current device driver and then reinstall the old device driver. As Microsoft Windows XP dos not offer the "Delete the driver software for this device." uninstall option, it might be useful to: delete TE03xx-USB*.sys and TE_USB_FX2*.sys files in the C:\WINDOWS\system32\drivers\ folder after uninstalling the current device driver and before installing the new device driver; delete oem*.inf files (along with their companion oem*.pnf files) in the C:\WINDOWS\inf\ folder corresponding to the relevant VID/PID after uninstalling the current device driver and before installing the new device driver.

33 2.2 Generic Cypress Driver Installation Most users don't need this driver, this driver is used only for initial USB microcontroller programming, which was already done for all supplied TE modules. If the USB microcontroller (Cypress EZ-ESB FX2) driver is not installed on the host computer, then the easiest way to do it, is the following: disconnect the module if it connected or leave the module unconnected; configure the module such that the USB microcontroller will provide its default vendor ID and device ID to the USB host. To do it, set EEPROM switch to OFF state (EEPROM disconnected from USB microcontroller). Refer to your module manual for switch location; connect the module to the host computer through the USB interface; wait until the operating system detects new hardware and starts the hardware assistant; set EEPROM switch to "ON" state (EEPROM connected to USB microcontroller); answer the hardware assistant questions as shown in the following example Check that, in the Device Manager under USB-Controller, the Cypress Generic USB Device has been added. After that, the I2C EEPROM should be programmed with the right Vendor ID / Device ID pair; see firmware recovery chapter in UM-Firmware.pdf. 3 Document Change History Version Date Author SP, FDR Initial release Sp, FDR Added XP, Vista.
